D. According to
W: Not yet. Are there a lot of changes?
M: There sure are. Instead of paying one fee to cover all meals for the whole semester, we are now able to choose by seven, ten, fourteen or twenty-one meals per week. They give you a card with the number of meals you get for a week marked on it.
W: That's a big change, and a complicated system.
M: Yeah. But it will be much better for people who don't eat three meals a day , seven days a week in the cafeteria, like me, because they don't have to pay for meals they don't eat.
W: So what's the deal for those who eat at school all the time?
M: It's better for them, too, because the more meals you contract, the cheaper each one is.
W: I see. It still sounds rather complicated.
M: True. It took me several hours to figure it out. I decided to go with the ten meals.
W: Why is that?
M: Well, I never eat breakfast and I often go away on weekends. So the ten meal plan gives me lunch and dinner each weekday at a fairly low price. And I won't be paying for meals I don't usually eat.
W: And what about the weekend when you are on campus?
M: Well, there are often guests on campus at weekends. So they allow you to buy single meals on a walk-in basis on Saturdays and Sundays. The price per meal is much higher in that way. But I am away so much that it will still be less money for me to pay single prices on the weekends rather than sign up for the fourteen-meal-a-week plan.
W: Oh, I guess I'll have to sit down and figure out my eating pattern so I can get the best deal.
